Chemistry Year 12 Random Retrieval

This quiz contains all the questions in the year 12 chemistry section. The website will pick 10 questions at random.

1 / 10

What is the product of the reaction of but-2-ene with steam in the presence of a phosphoric acid catalyst?

2 / 10

What is the mechanism for the reaction of bromine with prop-1-ene?

3 / 10

What is made by heating propan-1-ol under reflux with excess of a hot acidic solution of potassium dichromate(VI) and then distilling off the product?

4 / 10

Which of these pairs of compounds react to form 2-bromopropane as one of the products?

(i) prop-1-ene and hydrogen bromide at room temperature

(ii) propane and bromine in ultraviolet light

(iv) propan-1-ol and hydrogen bromide on heating

5 / 10

Using enthalpies of formation ΔfH, calculate the enthalpy of combustion ΔcH of ethanol:

C2H5OH(l) + 3O2(g) => 2CO2(g) + 3H2O(l)

Select the data from the 'Selection of Enthalpies of Formation and Combustion' shown above.

If this question was generated from Random Retrieval, this data can also be found in TOOLS>Data Sheets.
